奥氏体化温度对双相ADI中残余奥氏体含量的影响

摘要

The residual austenite has significant influence on the mechanical properties of Dual Phase Austempered Ductile Iron （ADI）. We address the effects of austenitizing temperature on the content of retained austenite in ADI with X-ray method to investigate the relationship between process, organization and performance. Results show that the content of retained austenite .qradually increases with the increase of austenitizinq temperature.%残余奥氏体对双相等温淬火球墨铸铁（ADI）的力学性能影响比较显著。为了进一步了解工艺-组织-性能的关系，利用X射线法研究了奥氏体化温度对双相ADI中残余奥氏体含量的影响。结果表明随着奥氏体化温度的升高，残余奥氏体的含量逐渐增大。
